If you ever laid a few magnets on a table and seriously wondered about their combined magnetic field... Looking for some Pic2Mag beta testers to test the newest Field Calculator program with 12 processing threads. Message me and I will send you the newest v1.04 program version.

I think it might actually be for the reason that OP wants $9.95 to use the full version of the software. I wonder if OP knows that there are better tools which are open source. This is one of those situations where I think OP would better enrich him/herself by open sourcing the project, consequently creating a much better tool, and putting that on the resumé.

It's irrelevant, but let me just add that "with 12 processing threads" is sort of a funny phrase to read. OP seems to be designing software which is scalable, but doesn't scale. It seems to be optimized for hexacore cpus only (so we can assume that OP is probably using an eighth generation intel processor). An open source development model would probably solve that problem right away; it's not that hard to query the number of logical cores available. If nothing else, OP should really learn to use a proper GPGPU compute library, because massive parallelism would be extremely helpful for a problem like this, and nobody would have to read such funny sentences as those which treat the number of threads a program is designed to spawn as a feature highlight.
